Application filed August 2, 1915.

To all whom t may concern:

Be it known that I, CHARLES F. SoHNAsA, a citizen of the United States,residing at Evanston, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Lawn-Sprinklers, ofwhich Il do declare the following to be a full, clear, and exactdescription, reference being had to the accompanying drawing, forming apart of this specil'ication.

Figure l is an end view of a lawn sprinkler embodying my invention. Fig.2 is a view in vertical cross section on line 2 2 of Fig. 3. Fig. 3 is aview in side elevation.

In the sprinkling of lawns, particularly such as are bordered orintersected by walks, it is desirable to provide a sprinkler that willthrow a flat or fan-shaped spray of water in order to sprinkle the grassup to the edge of the walk without wetting the walk itself. It is alsodesirable that the sprinkler shall be equipped with means for throwing arose or circular spray to cover as wide an area as possible when thesprinkler is operating upon portions of the lawn at a distance from theborder or walk.

The present invention has for its object to provide a lawn sprinklerthat shall be adapted for sprinkling both the body portion of the lawnand those portions of the lawn adjacent borders or side walks.

The invention consists in the novel construction of sprinklerhereinafter described, illustrated in the accompanying drawing andparticularly pointed out in the claims at the end of this specification.

My improved lawn sprinkler comprises two sprinkler heads A and B thatare mounted upon a common base or support C. The base or support C ispreferably in the form of runners, the upper portions of which are castintegral with the sprinkler head In the preferred form of the invention,the sprinkler head A is a tubular casting open and threaded at one endto form a coupling t into which the coupling at the end of the rubberhose may be fitted. The opposite end of this sprinkler head A is closedand adjacent the closed end is formed a semicircular slot a throughwhich the water admitted to the interior of the sprinkler head will passin a flat or fan-shaped stream or spray. Above the sprinkler head A ismounted the sprinkler head B. This sprinkler head preferably consists ofa circular casting having a short coupling b at one side Specificationof Letters Patent.

for attachment thereto of the coupling at the end of the hose. Theinterior of the sprinkler head B is shown as formed with a centralprojection b and with a top central orifice b2 through which the waterwill pass in a rose-like spray. The chambered upper portion of thesprinkler head B is similar to the familiar cyclone sprinklers now incommon use. The lower portion of the sprinkler head B is provided withdepending lugs or feet 3, the oppositely iiaring ends of which areformed with holes through which pass the retaining bolts D. whereby thesprinkler head B is connected to the common support C, suitable nuts Zbeing provided for the ends of these bolts. As shown, the lugs orfeet o3are cast integral with the body of the sprinkler head B.

In the use of my improved lawn sprinkler, when a portion of the lawn isto be sprinkled at a distance from a border or sidewalk, the hose willbe connected to the coupling o of the sprinkler head B, but when theportion of the lawn adjacent the border or walk is to be sprinkled, thehose will be connected to the coupling a, of the sprinkler' head A andthe water will be thrown in a fan-like spray or sheet parallel with andadjacent to the edge of the walk.

My improved lawn sprinkler provides a simple, cheap and eective meanswhereby a lawn may be sprinkled without danger of wetting the sidewalkadjacent the lawn. By forming the sprinkler heads separate andconnecting them together, the parts can be readily formed of cast metaland thus the cost of manufacture can be reduced to the minimum.

It is obvious that the precise details of construction above set out maybe varied without departing from the spirit of the invention andfeatures of the invention may be employed without its adoption as anentirety.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is- 1. A lawn` sprinkler comprising a cornmonbase or support and two sprinkler heads mounted one above the other uponsaid base or support, the lower one of said sprinkler heads having atubular bore provided with a coupling at its open end and providedadjacent the top. of its closed end with a discharge orice for throwinga substantially fanshaped spray, the upper one of said sprinkler headsbeing provided in its top with a discharge orice for throwing a circularspray, said upper sprinkler head having at one end a coupling and havingits opposite end outy of line with the oriice at theclosed end of thelower sprinkler head.

2. A lawn sprinkler comprising two sprinkler heads formed separately andsecured together one above the other, one of said sprinkler heads beingof tubular shape and having adjacent its closed end a transverse slot initsY upper portion and the other of said sprinkler heads being mountedabove said firstvnientioned sprinkler head and being provided with acentral discharge orifice in its top7 the upper sprinkler head havingitsvclosed 'endterminating outside the plane of said transverse slotinsaid lower sprinkler head.

3. AV VlawnV `sprinkler comprising twoy sprinkler heads one arrangedabove the other and each formed of a separate casting, one of saidsprinkler headshaving a tubular bore and having adjacent its closed enda transverse slot in its upper portion,

and the other of said sprinkler heads having a yoke-shaped lower partsetting over said first mentioned sprinkler head, means for connectingsaid sprinkler heads together and a common base or support for holdingsaid sprinkler heads in their proper relative positions.

4. A lawn sprinkler comprising two sprinkler heads, one of saidsprinkler heads consisting of a tubular casting closed at one end andopen at its opposite end and provided adjacent its closed end with atransverse slot in its upper portion, and the other of said sprinklerheads comprising a chambered casting formed at its top with a centralorifice and having an induction port, said casting being provided withdepending lugs, a common base or support for said sprinkler head andmeans for connecting said lugs to said base or support.
